APPARATUS FOR REMOVING WATER FROM WATER-BEARING SAND.

Specification of Letters Patent.

Patented Feb. 6, 19117.

Application filed June 5, 1916. Serial No. 101,670.

To all whom it may concern:

Be it known that '1, JOHN M. FERRY, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Apparatus for Removing Water from Water-Bearing Sand, of which the following is a specification. I

This invention relates to improvements in apparatus for removing water from waterbearing sand, and has for its object to provide a simple .and efficient device whereby the water can be removed from the sand ahead of the work in the construction of sewers, conduits and the laying of sewer or water pipes.

The invention consists of the novel construction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specification and pointed out in detail in the appended claims.

In the accompanying drawings,

Figure 1 is a plan View of a portion of a trench in which sewer pipes are to be laid and showing the application of my invention thereto.

Fig. 2 is a section on the line XX of Fig.

, Fig. 3 is a detail'view of one of the well points and the flexible connection at the top thereof.

Fig. 4 is a detail vertical section, on an enlarged scale, of a portion of the main line sections, showing one of the valves to which the well-points are connected.

Fig. 5 is a detail view, on an enlarged scale of one of the well points wit a portion of the wire screen removed therefrom.

Referring to the accompanying drawing 40 forming part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, 1 designates the pump house in which is located a pump 2 and a motor 3 for operating at said pump. The main suction line is made up of a number of sections 4 each connected by a gate valve 5* and the said main suction linebeing connected with the pump 2 by a pipe -6 on each side of which at the point where it connectswith the said main suction pipe is a gate valve 7 Each section 4 rated at 11, said perforations being covered with a very fine wire meshed-screen 12 through which the sand cannot pass. These points are driven into the sand at suitable intervals along the work and the suction created by the pump 2 causes the water to be drawn through the screen 12 and apertures 11 into the main suction pipe and then through the pump 2 and discharged through the discharge pipes 13 and 14. It will thus be seen that as the work progresses the sect-ions 4: are disconnected and moved to the other end of the main line and when the work has progressed sufficiently the said pump house ismoved along the work.. It

will be seen that by the use of my invention the water is being constantly removed as the work progresses and the difficulties which are usually encountered by the presence of water in the sand are obviated.

Having thus described my invention, what I claim 1s:

1. The combination of a main pipe line comprlsing a number of independently connected detachable sections, a pump, a pipe connectingthe pump with the main pipe 5 line, a number of perforated pipes adapted to be driven into the sand, and flexible connections between said perforated pipes and the main pipe line.

2. The combination of a main pipe line comprising a number of sections, a gate valve between each two sections, a pump, a pipe connecting the pump with the main pipe line, a number of valves in each of the main pipe line sections, a number of perfo rated pipes adapted to be driven into the sand, and a flexible connection between the said perforated pipes and the Valves of said main line sections.

3. The combination of a main pipe line comprising a number of sections, a gate valve between each two sect ons, a pump, a

Arranged along the section 4 55 pipe connecting the pump with the main main pipe line sections, and a discharge pipe pipe line, a number of valves in each secleading from said pump.

tion of the main pipe line, a number of In testimony whereof I affix my signature perforated pipes adapted to be driven into in presence of two Witnesses.

said perforated pipes and a valve of the SHELMA BEWLEY."
